Application April 20,

1 Claim.

This invention relates to fountain pens, the general object of the invention being to provide means whereby a capsule, lled with ink by a manufacturer, can be easily inserted into ythe barrel of the pen and the interior thereof placed in communication with a feeding part, leading to a nib or point by the user and without soiling his hands or requiring the use of tools and withrequired in pens as now formed.

The invention also consists in certain other features of construction, combination and arrangement of the several parts, to be used hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detail reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Fig. 1 is an elevational view of the improved pen.

Fig. 2 is a section on line 2-2 of Fig. 1.

Fig. 3 is 'a view of the feeding device.

Fig. 4 is a view of the ring which carries the holding clip.

Fig. 5 is a view of the plug member which carries .the point or nib and to which the capsule is to -be connected.

Fig. 6 is a view of the capsule.

Fig. 'l is a view of the nipple for the capsule.

In these views, the numeral I indicates the barrel of the pen and the numeral 2 indicates a plug member threaded into the open end of the barrel. This plug member has a collar 3 surrounding an intermediate part thereof which has a notch 4 therein for a purpose to be described. This collar abuts the end of the barrel, as shown in Figs. 1 and 2 and said plug member has the part projecting from the barrel formed with a cylindrical part 6, a threaded part 'I and a reduced cylindrical part 8. A cap 9 is provided for enclosing the point carrying parts and said cap is interiorly threaded as at I0 for engaging the threaded part 'I of the plug member and a smooth end part II for engaging the smooth part 6 and this smooth part II will frictionally fit a reduced part I2 at the rear end of the barrel, when the cap is placed on this end of the barrel when the pen is in use.

The plug number 2 has a bore therethrough for receiving the feeding member I3 and a part of the nib or point I4. This feeding member is of substantially conventional form and is formed with the usual passage I5 and it may be provided out the use of sacks, pump parts, etc., as are 1940, serial No. 330,757

(cl. 12o-42) with the grooves or slots I6. Its inner end is reduced to pass through the reduced tubular part I'8 at the rear or inner end of the plug member. A conical recess I9 is formed in the rear end of the plug member and this recess surrounds the forward part of the reduced tubular part I8.

The capsules are filled with ink by a manufacturer of ink and Ithe user of the pen buys these capsules for insertion in his pen. Each capsule hasa rubber nipple 2I fitted fluid tight in its open end. This nipple has a conical outer end and it is sealed immediately after the capsule is filled.

After the seal has been removed the nipple is forced over .the reduced tubular part I8 and the conical part of the nipple is forced tightly into the conical recess I9 so that a fluid tight joint is formed between the capsule and the plug member. The tubular member I8 may be grooved as, shown to receive a part of the rubber nipple to increase the sealing effect.

When the capsule has been so connected with the plug mem-ber the ink will fiow from -the capsule through the feeding member to the point or nib and in order to keep the point or nib at the., outer end of the feeding member from drying out when the pen is' being used or is lying unused without the cap thereon I provide a small cap which fits tightly on the part 8 of the outer part of 4the plug member and has a small hole in its small and outer end for the passage of the point of the nib.

A spring 21 is located in the rear end of the barrel and presses against the closed end of the capsule. This spring prevents the capsule from becoming loose when the pen is jarred by being carried or dropped.

' A ring 28 surrounds the collar 3 and has an interior projection 29 for engaging the notch d to prevent turning movement of the ring on the collar. A substantially U shaped spring 30 has one limb connected to an exterior projection 3l on the ring and a holding clip 32 is connected to the outer limb for holding the pin in the pocket of a garment. The clip 32 is centered directly above the nib so that when the pen is in use the clip will be between the thumb and the forei'lnger gripping the pen. As the clip is permanently attached to the pen proper at this point it provides a gri-p for unscrewing the cap barrel and also prevents the rolling of the pen when the pen is placed on a slightly inclined surface. The spring 30 acts to press the ball of the clip against the barrel and allows the ball to 'be raised from the barrel when the barrel is being unscrewed. It also makes thevballgrip'the clothing l more securely. Tue'capsule as wellas the barrel and its cap are'preferablymade of transparent materialesuchasfPyralin. f

Itis-thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be lunderstood that changes may -be made in the construction, combination and arrangement of the several parts, provided such A fountain pen comprising a' transparent bar- 1 y rel, a plug member tting in the open end of the barrel, a 'feeding member and nib carried by the plug member and projecting fromthe outer end thereof with the feeding member projecting from the inner end of the plug member, a capsule' containing ink tting in the barrel and having an outlet removably iitting over the last mentioned endl of the plug member, a removal capenclosing the projecting end of the plugv member and the nib and a cap tting over the outer end of the plug member and having a hole in its outer end for passage of the -tip end oi.' the nib therethrough.
